WAN Coax Connection Speeds
This section displays the TG590 Router’s Tx and Rx speeds (in Mbps).
Internet Protocol
This section includes three options: No IP Address, Obtain an IP Address Automatically, and Use the
Following IP Address.
No IP Address Select this option if the connection has no IP address. This is useful when the connection is
operating under a bridge.
Obtain an IP Address Automatically Select this option if the ISP requires the connection to obtain an IP
address automatically. The server assigning the IP address also assigns a subnet mask address, which can be
overridden by clicking in the “Override Subnet Mask” check box and entering another subnet mask address.
Additionally, the DHCP lease can be renewed and/or released by clicking on the appropriate “DHCP Lease”
button. The “Expires In” value displays how long until the DHCP lease expires.
Use the Following IP Address Select if the WAN connection is configured using a permanent (static) IP
address. The ISP should provide this address, along with a subnet mask address, default gateway address,
and, optionally, primary and secondary DNS server addresses.
DHCP Lease
Renew or release the current DHCP lease by clicking on the appropriate button.
DNS Server
The Domain Name System (DNS) is the method by which website or domain names are translated into IP
addresses. The connection can be set to automatically obtain a DNS server address, or an address can be set
manually, according to information provided by the ISP.
To configure the connection to automatically obtain a DNS server address, select Obtain DNS Server Address
Automatically from the “DNS Server” drop-down list. To manually configure DNS server addresses, select Use
the Following DNS Server Addresses. Specify up to two different DNS server addresses, one primary, the
other secondary.
